Dr. John Chunn MD, FAAP

Board Certified Pediatrician

Dr. Chunn is one of the longest tenured physicians at COPA, joining Dr. Mary Brown more than three decades ago. He continues to consult with COPA physicians on complex cases and is on call as needed, however, he is no longer at the clinic full time nor is he taking new patients.

The focus of Dr. Chunn’s career as a pediatrician was to help parents raise their kids effectively while supporting a lifetime of good health. For many years, Dr. Chunn was the region’s leading infectious disease specialist. In addition, he served as a renowned NICU (neonatal intensive care unit) specialist and is a former Chief of Pediatrics at St. Charles Health System.

His medical expertise and commitment to the health of all children remains a guiding influence at COPA among physicians there today.

Outside of his practice at COPA, Dr. Chunn — a father of seven — is an “extreme” outdoor enthusiast and a bit of an adrenaline junkie. He enjoys all types of skiing plus bicycling, running, weight lifting, mountain climbing and playing rugby.
